Necessity has been inventing again .... FYI, I have just added a new small utility to the ImageDisk package - this is called "ImageDisk Viewer" (IMDV). It is essentially a simple HEX editor that lets you easily poke through .IMD images with HEX displays accompanied by either ASCII or EBCDIC translations. Addtional features include the ability to search the image for specific strings, and to extract and view all printable strings from any arbirary location in the image (including scanning the whole image) - this is VERY handy when you are trying to figure what the heck a particular disk image contains. It's a simple viewer, but it's advantage over fancier dump utilities is that it knows about the .IMD format and can search/scan in the correct order for interleaved sectors (or not if you don't want), and scans/searches transparently across sector boundaries. If you have a reason too (or even if you don't), you can also use it to patch the content of individual sectors within the image (I take no responsibility...)
